master terminals

Hi all,

I am trying to write code that creates a list of pins on masters that
do not match schematic.
I have found it to work sometimes. Basically, If I change a name of
a pin on a master it catches that everytime. If a pin is missing, it
doesn't always catch it. I can delete a pin in a master(made sure
all pins are missing for the net) and run the code(at the parent"top")
and it doesn't catch the missing pin. Do the same thing on another
instance and the code catches the missing pin.

I don't think it is my code since I can take the one master that my
code doesn't catch a missing pin and run the below code and it isn't
caught that way either. It seems to me if the pin on a master is
deleted and you go back to the parent the pin information would be
gone, but that is not what I am seeing. I tried to update components
and nets, this doesn't change the results. Also, running
connectivity-->check-->against source doesn't catch the missing master
pin.

Any ideas why? Looks like I might have to write a script that checks
for pins at the master level using the schematic list of pins as a
"gold" list. yuk.

Thank you in advance for any help,

I'm assuming you are using VLS-XL (you write about update components and
nets).

Are you trying to create instTerm on instances which have a schematic
equivalent but whose schematic equivalent doesn't have an equivalent
instTerm? Or are you trying to create instTerm on instances which don't
have a schematic equivalent.

In the first case, I'd consider puting a net expression on the terminal in
the master of the layout instance. VLS-XL will create the instTerm for
you, resolving the netexpression in the schematic context. (This is used
for instance for bulk terminals on transistors).

I'm sorry but I didn't understood your problem. And I haven't the time to
check your code to see if I can guess the problem with its help.

If you are using 6.1.3, check the bnd* functions (IIRC, they were already
in 6.1.2 but I can't get confirmation now). They may help you.

Yours,
